Ardgreenan Drive appears as early as 1907 in the Irish News and Belfast Morning News, marking its development in the early 20th century during Belfast’s period of suburban expansion. The name “Ardgreenan” may be derived from the Irish Ard Grianáin, meaning “height of the sunny place” or “high sunny spot,” which suggests a desirable, elevated residential setting.
Another possibility is that the name may have originated from an earlier Scottish placename brought to Belfast in the 19th century. A house named Ardgreenan stood in the Cavehill area during the late 1880s. It is possible this name may have been the inspiration for the Ardgreenan streets in the Belmont area. One of the Cavehill houses bearing this name was, around the time the first of these streets was laid out, the residence of a widow from the prominent Riddel family (of Riddel’s Arcade and other Belfast landmarks), adding further social significance to the name’s transmission. The difficulty with this theory is the lack of obvious link between the two parts of the city.
"The Surveyor submitted the following names for new streets on the Wandsworth Road side of the Corporation’s Housing Scheme:
Campbell Park Avenue – Wandsworth Parade
Ardgreenan Gardens – Ardgreenan Place, Wandsworth Crescent, Wandsworth Place and Ardgreenan Crescent
Resolved: That the names be approved". (14th February 1922).
